Benny who was clearly in his 80's had just finished his morning jog and he didn't even appear to be short of breath.
Sam a 70 year old who was watching him was amazed at the man's stamina and asked him what he did to have so much energy.
Benny said, "Well, I eat rye bread every single day. Rye bread helps keep your energy level high, and it also gives you great stamina with the ladies."
Sam the 70 year old man was impressed, so on the way home he stopped at the bakery.
As he was looking around, the saleslady asked him if he needed any help.
He replied, "Do you have any rye bread?"
She said, "Yes we do, there is a whole shelf of it over there. Would you like me a get you some?"
He said, "Yes please, actually I would like five loaves."
"My goodness, five loaves!" she said. "By the time you get to the 3rd loaf, it'll be hard."
The man replied, "I can't believe that everybody knows about this but me!
